One key element of strategy in THe Lord of the Rings Trading Card Game is surprise. If your opponent can guess your every move, he can plan ahead and attempt to thwart you at every phase of the game. A good opponent will always check out the twilight pool left after the shadow phase and calculate what you can do with it. A drawback of the Raider culture is that most of the events have a cost and there are few enough events that a good player can remember them AND their cost and calculate why twilight has been left in the pool.
